Chrome Remote Desktop to Blender Server
It's true that RDP only presents a standard VGA driver, but Blender will still be able to take advantage of the graphics card to do its rendering, etc.

It won't be the best solution, but it'll be quite a cheap solution.

If you want to take it all a bit more seriously, you'd have to invest either in decent computers with a good graphics card and RAM, etc., or look into setting up Blender as a server, which I understand is also possible.
